SMM TiN magnets
I recieved 20 today. Just like everyone else I had a dark ring on one side. It seems like it alternates sides. Some of them are on the south side and some are on the north. It rubbed them with a microfiber cloth and got some of it off but there's still rings on them. I put 15 on separate containers with a little salt/soap water about 6 hours ago.
After looking at everyone else's posts and even know I want to implant one soon, they will spend 90 days soaking.

I'd highly recommend hitting a couple with polishing paste. No more soot, shinier, cleaner looking magnet.
Did you ask them if they were going to use a coating under the TiN? They frequently do for structure support and because many manufacturers buy precoated magnets. Please refer to my comment in the "magnet status" thread, it relates to this subject
Who's spamming? I haven't seen anyone spamming. Being talkative isn't the same as spamming.
of the 15 magnets I put in separate containers
All of the magnets still have strong fields. I'll update in a week or so
Well if 4/5 fail then doest that leave you with on average two good enough for implant with a pack of ten? Because I want to buy 20 test them well and I should end up with at least one good enough for implant. Theres a lot of people who have had success with them, so I'm not ruling SMM out yet. But thanks @cassox for pointing out the flaws, defiantly helps to know that not all SMM magnets are good.
Which tests have they failed? I've had 4 polished ones in a bottle of detergent+saline. 10 days in, they all look pristine to the naked eye. I'll check again with a microscope soon.
I started a batch of ten and two failed in 24 hours.
A week later, I started a batch of 20 and eight failed within 48 hours. I suspected that my saline solution was not mixed well and all the salt collected at the bottom and compromised the coating unduly, but hearing from Cassox makes me think that the magnets are failing as expected. Has anyone else been soaking their magnets and found anything?
Also, unless I'm mistaken, you need to have the current traveling through the thing you're trying to oxidize. The method that comes to my mind would be using a gold-clad pcb in a glass beaker as an electrode, putting magnets on top of it, with a piece of iron under the glass to hold the magnets in place. Then mask most of the gold around the magnets to minimize energy use, water evaporation, heat, etc. This would let you pass current through the magnets themselves
If any of y'all have any tips, I'll listen.
I mentioned the water with excessive salt. I have NO idea if this had any effect on the test. I was hoping someone could clarify for me.
When I mixed the salt water, I put a few grains of salt into my containers, added water, then tossed in a magnet. I never shook or stirred the salt and water and I saw swirls at the bottom where they had not mixed. Please don't make any assumptions about the effects of this extra-salty water and TiN.
